Just chast echo then shadow form and go agro and kill. I use it for killing npc in ab/FA/ and quarry. Recast shadow form when it expire. After second recast you can either run before it run out or time shadow form when it expire and death charge. Most likely you the kill when the 2nd shadow form end thus the "suicide" part of the name. It design for quick kill at your expense. This build is not toucher proof though. Also watch out for aoe area that was targeted at allies. One thing i found is that ranger ignite arrow and still hit you but only the ignite part the arrow deal no dmg.

One minor detail i forgot to mention, be sure you have at least 10 energy rdy for second shadow form or else it a early grave.

basically it great for quarry bc solo cap

arcane echo shadowform has been known for a very long time. You aren't the first to come up with it and you won't be the last.

Ive use a build like that, it's a fun classic

IoW to cover shadow form when it ends.
